Generally, the pixel pitch of Large LED Display used indoors is below P5, while those with pixel pitch of P2 and below are called fine pitch LED Screen, such as P2, p1.875, p1.667, p1.583.p0.96, etc. These full-color screens called fine pitch LED Screen are often used in places where the indoor viewing distance is closer, so this kind of LED Screen are often called high-definition LED Screen. Large LED Display above P5 are often used in outdoor display projects, such as P8 and P10 LED Screen specifications commonly used in the market.
